Title:
apparmor denial to several paths to binaries
Status in ntp package in Ubuntu:
Fix Released
Status in ntp source package in Artful:
Fix Committed
Bug description:
[Impact]
* Apparmor denies access to bin directories which the option parsing code
of ntp touches.
[Test Case]
1. get a container of target release
2. install ntp
apt install ntp
3. watch dmesg on container-host
dmesg -w
4. restart ntp in container
systemctl restart ntp
=> see (or no more after fix) apparmor denie:
apparmor="DENIED" operation="open" profile="/usr/sbin/ntpd"
name="/usr/local/sbin/" pid=23933 comm="ntpd" requested_mask="r" denied_mask="r"
apparmor="DENIED" operation="open" profile="/usr/sbin/ntpd"
name="/usr/local/bin/" pid=23933 comm="ntpd" requested_mask="r" denied_mask="r"
[Regression Potential]
* we are only slightly opening up the apparmor profile, but none of the
changes poses a security risk so regression potential on it's own
should be close to zero.
* we discussed if this would be a security risk but came to the
conclusion that r-only should be ok (the same content anyone can grab
from the archive by installing the packages)
[Other Info]
* n/a
Issue shows up (non fatal) as:
apparmor="DENIED" operation="open" profile="/usr/sbin/ntpd"
name="/usr/local/sbin/" pid=23933 comm="ntpd" requested_mask="r"
denied_mask="r" fsuid=0 ouid=0
apparmor="DENIED" operation="open" profile="/usr/sbin/ntpd"
name="/usr/local/bin/" pid=23933 comm="ntpd" requested_mask="r" denied_mask="r"
fsuid=0 ouid=0
Since non crit this is mostyl about many of us being curious why it
actually does do it :-)
